Add support for the new GOSUB DSB instruction (available on ptl+),
which instructs the DSB to jump to a different buffer, execute
the commands there, and then return execution to the next
instruction in the original buffer.
There are a few alignment related workarounds that need to
be dealt with when emitting GOSUB instruction.
v2: Right shift head and tail pointer passed to gosub command (chaitanya)
v3: Add macro for right shifting head/tail pointers (Animesh)
v4: Fix typo in commit message (Uma)
Add comments explaining why right shifting htp is needed (Animesh)

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
